Question 1.
What is mixing height?
Show hintHide hint
Think about how pollutants spread in the air.
Question 2.
Define atmospheric stability in simple terms.
Show hintHide hint
Consider temperature changes during air parcel movement.
3Question 3.
What does the mixing height refer to?
- The height of a building
- The altitude where pollutants mix
- The temperature of the air
Show hintHide hint
Consider where mixing happens in the atmosphere.
4Question 4.
True or False: The adiabatic lapse rate changes depending on the emission source.
- True
- False
Show hintHide hint
Think of the consistent value of the lapse rate.
Question 5.
Given that the adiabatic lapse rate is -0.0098 °C/m, calculate the temperature of an air parcel starting at 25 °C at an altitude of 1 km.
Show hintHide hint
Remember to account for the temperature change over the altitude difference.
Question 6.
Design an experiment to measure the mixing height in a given urban setting. What variables would you consider?
Show hintHide hint
Think about what affects air movement and pollution dispersion.
